The client-side automatic encryption settings.
The client-side automatic encryption settings. Client side encryption enables an application to specify what fields in a collection must be encrypted, and the driver automatically encrypts commands sent to MongoDB and decrypts responses.
Automatic encryption is an enterprise only feature that only applies to operations on a collection. Automatic encryption is not supported for operations on a database or view and will result in error. To bypass automatic encryption, set bypassAutoEncryption=true in AutoEncryptionSettings.
Explicit encryption/decryption and automatic decryption is a community feature, enabled with the new com.mongodb.client.vault.ClientEncryption type.
A MongoClient configured with bypassAutoEncryption=true will still automatically decrypt.
If automatic encryption fails on an operation, use a MongoClient configured with bypassAutoEncryption=true and use ClientEncryption#encrypt to manually encrypt values.
Enabling client side encryption reduces the maximum document and message size (using a maxBsonObjectSize of 2MiB and maxMessageSizeBytes of 6MB) and may have a negative performance impact.
Automatic encryption requires the authenticated user to have the listCollections privilege action.

A Scala based wrapper of the Observer interface which provides a mechanism for receiving push-based notifications.
A Scala based wrapper of the Observer interface which provides a mechanism for receiving push-based notifications.
Will receive a call to Observer.onSubscribe(subscription: Subscription) on subscription to the Observable.
Default implementations of this trait are greedy and will call Subscription.request with Long.MaxValue so that all results are requested. Custom implementations of the onSubscribe method can be used to control "back-pressure" and ensure that only demand that the Observer is capable of handling is requested.
After signaling demand:
- One or more invocations of Observer.onNext up to the maximum number defined by Subscription.request - Single invocation of Observer.onError or Observer.onComplete which signals a terminal state after which no further events will be sent.
